Statement of Methodology

This survey of 1,000 residents of the United States was conducted between September 6 and September 11, 2023, and is based on live telephone interviews of adults 18 years of age or older, residing in all 50 states and the District of Columbia. Quota and demographic information --including region, race, and age -- were determined from 2020 national census data. Samples of both cell phones and standard landlines were called using a probability-proportionate-to-size method, which means that the phone numbers assigned to each state were proportional to the number of residents in each state. States were grouped into four general regions. Surveys were administered in English and Spanish. The margin of sampling error for results based on the total sample is +/-3.1 percentage points. Error margins increase for smaller subgroups in the cross-tabulation document above. All surveys may be subject to other sources of error, including but not limited to coverage error and measurement error. The following Sawyer Business School students contributed questions for this survey: Tina Do and Joaquin Heller Della-Vecchia.

Statement of Methodology

This survey of 900 adults was conducted August 19-August 27, 2023, and is based on live telephone interviews of U.S. citizens 18 years of age and older residing in all 50 states and the District of Columbia. Each state’s non-voter quota was determined by subtracting actual votes cast in the 2020 presidential election from the VEP (voter-eligible population) in every state for the November 2020 election. States were grouped into 4 general regions per U.S. Census designations and each region was assigned age and race quotas. Telephone numbers were called from samples of both standard landline (11%) and cell phones (89%) using a probability proportionate to size method, which means that the phone numbers assigned to each state were proportional to the number of non-voter residents in each state. Results are statistically significant to within +/- 3.3 percentage points on the entire sample.
The error margin increases for subgroups/cross-tabulations which follow.

Statement of Methodology

The nationwide Suffolk University/USA TODAY surveys were conducted through live interviews of 600 Joe Biden voters and 600 Donald Trump voters identified from previous Suffolk University/USA TODAY national and state polls taken from 2020-2022. The separate surveys were conducted from April 15 to April 18, 2023. Demographics of the subsets of Biden and Trump voters correlated with demographic proportions of Biden and Trump voters from previous national surveys and 2020 exit polling data of Biden and Trump voters. Respondents were contacted using cell phones and landlines and were randomly selected by identifying and confirming voter information from previous surveys. Surveys were administered in English and Spanish. The margin of error for each 600-respondent survey is +/- 4 percentage points. Error margins increase for smaller subgroups in the cross-tabulation document above. All surveys may be subject to other sources of error, including but not limited to coverage error and measurement error.
